X-RAY OPERATING-TABLE.

Specification of Letters Patent. Application filed July 27, 1910. Serial No. 574,045.

Patented J an. 16, 1912.

To all whom, it may concern Be it known that I, EDWIN W. KELLY, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful X-Ray Operating-Table, of which the following is a specification.

My invention relates to X-ray apparatus,

' and particularly to apparatus whichmay be styled a table for use in the examination of patients under X-rays, or the like.

- My invention resides in a table, such as above referred to, which is equipped with means for supporting a source of radiations in any suitable or desired position, such table and its equipment being preferably portable or movable as a whole.

y invention resides in the hereinafter described.

For an illustration of one. of the forms my invention may take, reference is to be had to the accompanying drawings, in which:

Figure 1 is a perspective view of the table andit's equipment. Fig. 2 is a fragmentary view, in section, illustrating construction of a part of the table. Fig. 3 is a plan View, some parts in section, illustrating the X-ray tube supporting apparatus. Fig. 4: is a side. elevational view of the same, some parts in section. Fig. 5 is a detail view, partly in section, showing the mounting of a member for supporting the X-ray tube. Fig. 6' is a perspective view of plate shifting mechanism. Fig. 7 is a view, partly in section, of means for mounting a fluoroscopic screen in fixed relation with an X-ray tube. Fig. 8 is a longitudinal sectional view through means for shifting theX-ray tube upon its supporting apparatus. Fig. 9 is a longitudinal sectional view through means for shifting the tube supporting apparatus. Fig. 10 is a side elevational view, some parts in section, of plate shifting means shown in Fig. 6, together withparts of the table. Fig. 11 is a planview, partly in section, showing a latch or trigger for shifting means such asshown in Figs. 8 and 9.

Referring to Fig. 1, there is illustratedmy table with its equipment which, as a unit or as a whole, desired, the table proper and its equipment apparatus made of metal tubing connected by the vertical tubular members 3 and 4. Extending toward the front from the main frame 1, 2, 3, 4, are the end frames consisting of the front vertical tubular members 5 and 6 and .the lower horizontal tubular members 7 and 8, similar tubular'members joining the tops of members 5 and 6 with the vertical members 3 and 4.

Upon the lower 4, 5 and 6 are provided casters 9 upon which the apparatus as an entirety may be moved about, as upon a floor.

It will be noted that there are no members at the front of the apparatus joining or tying the end frame portions, thus constituting an open frame Within which a patient may be stood or seated, or otherwise placed, Without necessity for the patient stepping over or around'any part, the frame being rigid and self-sustaining without any such fronttying or connecting members. And it is characteristic that to provide such open frame no part in front need be swungput or moved away, for the purposes above mentioned.

The table proper comprises the table member 10 and the additional leaves 11, 12 and 13. The main table member 10 is pivoted at 14 upon brackets 15, one at the front and one at the rear,'supported upon the end may be moved about as frame members 4 and 5. A notched segment "member 16 is fixed to the main frame and in the different notches is adapted to engage the rod 17 passing loosely through the lugs 18 upon the member 19 secured to the main table member 10. The upper end of the rod 17 is connected to the horizontally extending rod 20 having at its front end a handle ends of the verticals 3,

21 by which the rod 17 maybe lifted out of any of the notches spring 22.-

r The main table member 10 is here illustratedas constructed of a frame formed by the tubes 23, the front and rear tubes 23 being secured in sockets 26 .upon the member in opposition to 27 hinged upon the pivot 14, a sheet of aluminum 24, or other suitable means transparent to the X-rays or other radiations employed, being stretched upon the tubular frame 23, the edges of the sheet 24 being wrapped around the tubular members 23, as illustrated in Fig.- 2, and secured thereto by screws-25.

At the top and bottom of the frame 10, as viewed in Fig. 1, are secured the rods 28 for supporting plate shifting apparatus hereinafter described.

By inserting the rod 17 in the different notches of the member 16, the main table member 10 may be held in any positionbetween the vertical and horizontal, and when in .horizontal position the sheet 24 of the table member 10 forms a substantially continuous surface with the leaf 12, and with the leaf 13 when the latter is in horizontal position.

When the main table member 10 is in Fig.

as seen in Fig. 1, rests upon pins 29, (see Fig. 10), supported by the horizontal tubular frame member 30 extending between the verticals 3 and 6.

The leaf 13 is pivoted to the member 30- by the hinges 31, and the leaf 13 may belet down to verticalposition or may be adjusted to any intervening position by the notched .members 32 pivoted thereon and actuated by the handle 33 to cause any of the notches to engage pins 34 upon the verticals 3 and 6. And, similarly, the leaf 11 is pivoted so as to be moved from the vertical position, shown in Fig. 1, to a horizontal position, the notched members 35 controlled by a handle 36 being adapted to engage pins 37 upon the verticals 4 and 5.

The vertical rigid member, 38, preferably of metal tubing, is provided with a socket member 39 between its upper and lower halves, the socket member 39 embracing the main frame tube 1 so that the member 38 and the parts carried thereby may be moved on tube 1 longitudinally of the table. To effect this longitudinal adjustment, a cord or chain 40 is provided and has its ends connected to the member 38, and passes oyer two pulleys or sprocket wheels, such as 41, 10, one supported by the vertical frame member 3 and the other by the vertical frame member 4. The right hand sprocket wheel 41 is secured upon a shaft 42 extending to the front of the table, where it has secured. thereto a crank 43, upon turning which the chain 40 is moved in the one direction or the other to adjust the member 38 longitudinally upon the member 1.

A tubular member 44 is rigidly supported at both of its ends upon the vertical a screw 46 is provided which clamps the upper bearing 45 snugly upon the member 44. At its lower end the member 44 is steadied against the frame tube 2 by a roller, or caster 47 secured upon the lower bearing 45. A shoe carried upon the lower end of the member 38 bears against the rear side of the tube'2, so that the members 38 and 44 are incapable of any rotary movement about the upper frame tube 1. Slidable vertically upon the member 44 is a tube supporting apparatus, such as shown in Figs. 3 and 4. The tube supporting apparatus comprises a member 48 embracing and slidable vertically upon the member 44. Attached to the member 48 or integral therewith, is a ring 49 upon which bears a split ring 50 which may be adjusted to differentdegrees of snuguess of 'fit on the ring 49 by the screw 51, Figs. 3 and 4. Several ears 52 are secured upon the inside of the ring 49 and engage the edge of ring 50 to prevent the same from becoming displaced from ring 49. The member 48 is in two parts, see Fig. 3, both engaging the member 44, the parts being held together by the screws 53, at the top and bottom of the member 48. To prevent the member 48 from adjustment vertically upon the member 44, that is, to lock the member 48 in desired position upon member 44, one of the screws 53 may be tightened by handle 54 for clamping the member 48 tightly against the member.44. There is cut in the external surface of the member 44 a vertically key 55 engaging in the member 48, the key 55, In consequence, preventing rotation of the member 48 upon member 44 in all positions of vertical adjustment of member 48 upon member 44. Upon the upper bearing 45, see Fig. 1, is mounted a sprocket wheel 56 secured upon the horizontal shaft 57 upon which is secured also the gear wheel 58 with which meshes a .pinion, not shown, secured upon the shaft 59 to which is secured the handle crank 60. And upon the lower hearing member 45 is pivoted the sprocket wheel 56*. A chain 61 is connected at its one end to the member 48 at 62, Fig. 3, and passes over the sprocket wheel 56 down into the bore of the member 44 within which is a counter-weight 63, see Figs. 3 and 4, to the upper end of which the chain 61 is attached. To the lower end of the counter-weight 63 is attached one end of the chain 61, which passes over the sprocket 56 and is attached at its other end to the member. 48. By turning the crank 60 the member 48 and attached parts may, therefore, be adjusted to any position vertically upon the member 44, the counter-weight serving to hold the parts stationary in any position, and member 44 may rotate in bearings 45 to swing the tube apparatus from above the table.

extending key-way adapted to receive the I The ring is movable cir'cumferentially upon the ring 49 attached to the member 48, so that the parts supported by the member 50 may be rotated to any part of an entire GilCUITlfQIGDCG about a horizontal axis.

Attached to the ring 50 are the horizontally extending bars or tubes 64 connected at their outer ends by a member65, which is used also for a handle for rotating the parts upon the ring 49. Slidable longitudinally upon the members 64 are the members 66 carrying the transverse bearings 67 in which bear cylindrical projections 68 upon a member 69 carrying lugs 70 in which engage the rods 71, held by set screws 72; upon thelow'er ends of the rods 71 is supported a ring or other open member 73 to which is secured a ring or other open member 74 of wood or other suitable material, preferably nonmetallic. The ring 74 is adapted to be compressed against the body of the patient.

Upon the under side of the member 69 there is pivoted at 75a holder 76 for diaphragms of diiierent apertures, and opaque to X-rays, a diaphragm 77 being shown in position in Figs. 3 and 4, resting upon the I corner webs 78 upon the diaphragm holder 76. The diaphragm holder is held in the position shown by a clip 79 secured to the member 69.

Upon'the other side of the member 69, within its flange 80, and concentric with the opening 81 in said member 69, is a felt or other soft or yielding washer 82 upon which rests the lower edge or flange of the shield 83, which may be of lead glass or other suitable material to cause absorption ofall the rays from the X-ray tube except those projected in desired direction. Theshield 83 is clamped in position against the washer 82 by two clamp members 84 secured together at 85-, the clamp members 84 adapted to surround the shield 83 and the members 84 secured to member 69 by thumb nuts 86. The shield 83 is open at its end 87 to' receive an X-ray tube 88, Fig. 1, having target 89. Theshield 83 has opposed slot openings 90 to receive the glass tubular projections 91.

upon the X-ray tube, which are held by clamps 92 supported upon the members 93,

- of fiber or other insulating material, secured,

of the bearings 68.

.asshown in Fig. 5, upon the cylindrical bearing projections-68 upon the member 69.

The member 69 and the shield 83 and A -ray tube 88 supported thereby, together with the other parts supported thereby or secured thereto, are swingable about the axis On a projection 94 upon the member 69, Fig. 3, is carried a graduated segment 95 with which cotiperates 7 a pointer 96 for indicating the degree of-inclination of the member 69 and attached parts. The member 69 may be clamped in any of its angularly adjusted positions 'by the thumb screw 97 which draws the pointer member 95,- the member 96 snugly against tlie side of the pointer 96 eing stationary with respect to the sliding. members 66. Projections 98 upon the sliding members 66 serve to receive the clamping bolt 99 which may be drawn up by the thumb nut 100 to draw the sliding members 66 toward each other, and thereby tightly grip the members 64, w ereby the member 69 and attached partsare clamped in any position of adjustment longitudinally of the members 64., To the ning 50, Fig. 3, is secureda rod 101 which extends parallel with the members 64, within a tube 102, Fig. 8. At its front end the rod 101 carries a leatheror other piston 103 fitting snugly within the tube 102, the latter movable freely through the guide 104 secured upon the member-'65, Fig. The left end of the tube 102, Figs. 3 and 8, is closed by a member 105 having a small perforation 106 communicating with the inte rior of the tube and serving to retard the exit of air from the tube 102 to one side of the piston 103. The rod 101 passes freely through a block 107 secured to and within the tube 102, and to the block 107 is connected one end of a spiral spring 108, whose other end is secured to the rod 101. Upon the outside of the tube 102 is a block 109 having lug 110 adapted to engage one of the sliding members a be adjusted to different positions on the'tube 102 and there secured by thumb nut 111.

At the right-hand end of tube 102, Fig. 8, is a block 112, screw threaded into the tube 102, and provided with an aperture sur-' rounding the rod 101. Pivoted at 113 upon theblock 112 is a latch plate114 having an extension 115 to which is attached a cord 116 passing through the eyelet 117. The rod 101 has a circumferential groove at 118 in which the latch plate 114 is adapted to engage, the latch plate 114 having an aperture allowing the free passage therethrough of the rod 101, A spring 119 is connected at its one end to the latch plate-114 and at its other end to the block 112, the spring urging the latch plate 114 to enter the groove 118. -This construction will be better understood byreference to Fig. 11, where a similar latch is applied to the apparatus shown in'Fig. 9.

\Vith the clamping bolt 99 loosened, so that the members 66 may slide freelyupon the member 64, and with the lug 11.0 engaging against a member 66, with the spring 108' under tensionand the latch 114 engaging in the groove 118, upon pulling the string 116 the latch plate 114 will be moved in opposition to spring 119, removing the latch 114 from the groove 118, whereupon the spring 108 will pull the tube 102 in the direction of the arrows, F igs.Y3' and 8, thereby,-m ov'in g the members 66, and therefore the-member 69 and attached parts, including the X-ray -13o 66. The block 109 may so verticallydownward parallelto the member .44 and attaches'to the rod- 101*, Fig. 9. The rod 101 extends into the tube 102? through tubefin the direction of the arrows, a distance of substantially 2% inches, the average distance between the human eyes, whereby an exposure may be made with the tube, first in one position-and then in the second position. The movement of the parts is accomplished without, shock due to the slow escape of the air from passage 106, the parts coma ingto rest in the shifted position without i -jar. By this mechanism, the X-ray tube -may be moved upoh the members 64 for stereoscopic exposures.""'"Practice may re- TI quire, however, that the X-ray tube shall not only be moved transversely to the table by the means described in connection with Fig. 8, but that the tube shall also be'mov-- I able a similar distance for stereoscopic exposures in a longitudinal direction. This is accomplished by a. similar -mechanism shown in section in Fig. 9, and shown in Fig.1 at the lower end of the member 44,

, whereby the member '38 and all attached parts, including the X-ray tube, will be moved longitudinally of the member 1 a desired distance for stereoscopic exposures.

Inthis case, a cord or chain 120, Figs. 1 and 9, has its one end permanently attached at Y r 121 to the main frame, and extends parallel with the tubular member 1 and over a pulley 122 upon-the member 39 and then extends a block 112 screw threaded into the tube 102. -.At its free end the rod 101 carries the leather or other piston 103 fit-ting snugly screw 123 having the tape'redpoint In the block 105 is securedthe-rod and tothe member 126 is secured one'en'd'of the spiral spring 108", surrounding the tube 102, and whose other-- end extends through a longitudinal slot 102, in tube 102 and is secured to the rod 101 within'the tube 102 The rod 101*,has a circumferential groove 118 in-which is adapted. to engage the latch plate 114, see Fig. 11, pivoted at 113 to the block 112. The'latch plate 114 has a projection115extending outwardly through an aperture, in the tube 102. and there is $61.

A sprin 119 is secured at its one end to the bloc 112 and at its other end to the latch plate 114*, the spring urging the latch to enter the groove 118 The operator puts the spring 108 undertension by moving the member 38 toward the left, Fig. 1, upon the member 1, thus pulling the rod 101 upwardly and bringing to the left'ias viewed in Fi 9, as indicated by the arrow. This, in e 'ect, pulls downwardly upon the cord 120 which, being fastened at 121, moves the member 39 and, therefore, the member 8 and all attached parts including the X-ray tube, toward the right, Fig. 1, upon member 1, the desired distance, whereupon the second exposure for stereoscopic purposes is made.

As is shown in Fig. 1, there is to the left side of the table member 10 a plate shifting apparatus for holding two radiographic or X-ray plates for successive exposures, particularly for stereoscopic work. This apparatusmay be secured on either side of the member 10 by attachments engaging the bars 28. When attached on the right-hand side of member 10, as viewed in Fig. 1, the exposures may be made with the patient sitting upon the leaf 12 with back against member 10, or may clining position with the member 10 closed down to make a flat table, the plateholding apparatus then being under the table. This plate. shifting apparatus'comprises the mam frame 127 havingsecured upon two of its sides the strips 128 and 129, the former terminating in the hooks 130 adapted to engage the rods'28, see Fig. 10. The latter strips 129 have their ends slotted as at 121 which are also'adapted to embrace the rods 28 and prevent the frame from separating there- \from. The strip 129 is divided into two \parts slidable upon the side of the frame {127, the en agement being by screws 132 passing free y through the slots 133 in said members 129. Approximate the center of turned ears 134 which may be gripped and forced toward each other in opposition to the spring 135, to withdraw the extreme ends of the members 129 to such position that upon release of the ears 134 the spring 135 will force the members 129 apart and cause the slots 131 to embrace the rods28.

On the inner sides of two of the sides of the frame 127 are provided two parallel guides 136, in the form of channels, in which engage the pins 137 carrying rollers 138 which roll in the channels 136. The pins 137 are secured in alinement with each other at one edge of the plate or member 139, of steel or other material opaque to the X-rays or other radiations employed. This plate is secured substantially midway between the plate holder supports 140 to which it is braced by the struts 141, the plate holder supports 140 and the plate 139 being in fixed relation with respect to each other and movbe made with the patient in rethe frame the twoparts 129 have outwardly ing as a unit. Where the sup orts 140 constring or rod 164 lifting the latch from the verge at one edge of the p ate 139, they pin 137, whereupon the springs 159 c'ontract are provided with lateral extensions 142 over and pull the rod 158 to the ri. ht, as viewed each of which slides a slotted member 143 in Fig. 10, thereby causing th e pins149 t carried by each of the plate holders 144, Fig. descend in the slots 150 in opposition to 10, the plate holders being omitted in Fig. springs 153, the plate 139 and the holders 6 for the sake of clearness; As appears in 140 in the meantime rotating about said pins section in Fig. 10, 145 is the one cover of the 149, and the pins 137 movmg along in the plate holder opaque to ordinary light, channels 136. When the pins 149- have against which is shown the radiographic or. reached the lower limit of their travel, the X-ray plate 146 covered by a secondcover springs 153 are under their maximum ten 147 of aluminum or other material opaque sion, and the pins 137 are directly in a vertito ordinary light but transparent to X-rays cal line with the pins 149, as viewed in Fig. or other radiations employed. 10. The further movement due to springs At the outer ends of the plate holder sup- 159, carries the apparatus past this deadso porters 140 are provided pins 148 which encenter position, whereupon the springs 153 gage in the plate holders 144 to hold them contract and cause the plun'gers-155 to again in fixed relation to the supporters 140. rise in the tubes 151 retarding the continued At the other edge of the plate or member motion.

rescent material 169 mounted upon the lead glass 170 or upon any other transparent material which, however, absorbs the X-rays or other radiations employed. By this means the operator may look directly at the screen without any of theradiations penetrating to him, a diaphragm being employed to confine the radiations within the limits of the screen. The apparatus just described affords mea.ns for moving the X-ray tube and screen, always in fixed relation to each other, to difierent positions while the patient remains stationary, for exploring purposes. The operator, by gras ing the handle 166, and with the clamps 9 7, 100, 51 and 46 loosened, may move the tube freely, and his screen is always maintained in fixed relation thereto.

By the construction herein. shown the X- ray tube carried by the members 64 maybe moved the entire length of member 44 and be disposed either above or below thetable Indeed, the tube may be lowered to such position that the main table member 10 may be lowered to horizontal position with the tube completely below the same. And in view of the open frame construction heretofore referred to, the members 64 carrying the X-ra-y tube, may be thus lowered to position beneath the table without engaging or connecting any tying member.

When the tube is below the table member 10, the'latterbeing then in horizontal position, the patient is above and upon the table 10 and the radiographic plate is held above the patient by an arm 50 adapted to 50, see Fig. 4. Or this arm 50* may carry the plate shifting apparatus, such as shown in Fig. 6, for stereoscopic purposes.

It will be noted also that the main tubular member 1 and members 44 and 64 have engraved thereon suitable scales to assist the operator in setting and operating his apparatus. v

The table herein described is intended to be of universal application; and to be capable of all the operations which heretofore have required separate and distinct pieces of apparatus.

The apparatus herein described is a unias aforementioned, all the adjustments and features making the operations which heretofore have only been possible in different pieces of apparatus.
